Description
-----------

Analysis of variance (ANOVA) is used to analyze the differences between group means and their associated procedures,
in which the observed variance in a particular variable is partitioned into components attributable to different sources of variation.

Input files

+---------------------------+------------+
| Parameter : num + label   |   Format   |
+===========================+============+
| 1 : Data Matrix file      | Tabular    |
+---------------------------+------------+
| 2 : Sample Metadata file  | Tabular    |
+---------------------------+------------+


------------
Output files
------------


***.anova_pvalue.tabular**

    | A tabular file which represents for each metabolite (row), the value of the intensity in each sample (column) + two columns (aovPValue and aovAdjPValue).

***.anova_filtered.tabular**

    | The tabular file xset.anova_pvalue.tabular containing only the metabolites that have been filtered by aovAdjPValue.


------

.. class:: infomark

The outputs ***.anova_filtered.tabular** or ***.anova_pvalue.tabular** are tabular files. You can continue your analysis using it in the following tools:
    | PCA
    | Hierarchical Clustering
